LED照明技术在飞机外部照明系统中的应用分析

外部照明是飞机照明系统的一个重要组成部分,在飞机起飞、巡航、着陆等过程中为其提供空中信息。外部照明对灯具的性能要求很高,如高强度、抗振动、长寿命、高可靠性等,且不同灯具实现不同功能,有特定的光分布要求,而采用传统光源的外部照明难以满足这些不断提高的技术要求。LED照明具有高亮度、低功耗、长寿命等技术优势,有助于促进飞机外部照明技术更好的发展。对LED照明技术及飞机外部照明系统的特点进行了分析,探讨了LED照明技术在飞机外部照明系统中的应用优势与前景。

Application of LED Technology in Aircraft Exterior Lighting

Exterior lighting system,which plays an important role through the process of taking off,flight and landing to provide information of the airspace,is an essential part of the aircraft lighting system. Lights in the exterior lighting system desire high performances,including high intensity,high vibration resistance,long lifetime and high reliability. Each of the lights is used to accomplish different function,hence requires different light distribution. Traditional lamps,which have been dominating the aircra...
